Hubble takes a grand tour of the solar system

The NASA/ESA Hubble Space Telescope has completed its annual grand tour of the outer Solar System. This is the realm of the giant planets—Jupiter, Saturn, Uranus, and Neptune—extending as far as 30 times the distance between ...

A small telescope past Saturn could solve some mysteries of the universe better than giant telescopes near Earth

Dozens of space-based telescopes operate near Earth and provide incredible images of the universe. But imagine a telescope far away in the outer solar system, 10 or even 100 times farther from the sun than Earth. The ability ...

Did Titan give Saturn its tilt?

Giant planets like Saturn don't just tilt over all by themselves; something has to knock them over, or tug on them gravitationally, to push them off axis. Scientists expect that when new planets are born, they form with almost ...

Saturn makes waves in its own rings

In the same way that earthquakes cause our planet to rumble, oscillations in the interior of Saturn make the gas giant jiggle around ever so slightly. Those motions, in turn, cause ripples in Saturn's rings.

Icequakes likely rumble along geyser-spitting fractures in Saturn's icy moon Enceladus

Tidal stresses may be causing constant icequakes on Saturn's sixth largest moon Enceladus, a world of interest in the search for life beyond Earth, according to a new study. A better understanding of seismic activity could ...
